The G12 GM Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic G12 GM-Series achieves 80 PLUS® Gold standard of providing at least 87 %, 90 % and 87 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the G12 GM series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the G12 GM units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC).

80 PLUS GOLD
The G12 GC achieves 80 PLUS Gold certification with its 90 % efficiency at 50 % system load.

S2FC - SMART AND SILENT FAN CONTROL
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
